Application led October 30, 1922. Serial No. 591736.

A To all wlwm it may 'concern/.-

Be' it known that I, PATRICK .I-I. CAL' LAGHAN, a citizen of the United States, re-

-Siding aft' Philadel hie, in the county of Philadelphia and tate of Pennsylvania, have invented certain new and useful Improvements in Bearings, of which the following is a specification.

My invention relates to' anti-friction bearings of the type in which the rollers are arra d in circular series. i

e object of the invention is to provide an improved, novel and simple construction of roller nearin in which the rollers are so placedas to re uce friction to a' minimum,

and so assembled as to prevent binding or angular displacement.

` which will be described hereinafter, I attainl in "the following manner, reference being This object, and other advantageous ends had to the accompanying drawings in which- Y Figure 1 is an. end elevation of my improved roller Figure 2 is a sectional viewtaken on the line 2 2 of Figure 1, and Figure 3 is va central sectional view taken through Figure'2.

In the drawings, 5 Iis a sleeve adapted to be secured upon a' shaft or other supporting element and provided midway between its ends with an annular peripheral rib 6, preferably of convex cross section. A. series of rollers 7 is disposed about the sleeve, each having, midway of its ends, an annular with the cylindrical parts of the sleeve, and

reduced cylindrical ends l() which serve as trunnions. Another series of 'rollers 11 preferably of larger diameterl is disposed around rollers 7, each having midway of its ends a rib 12 conforming-n contour with the grooves in rollers 7, drical parts 13 adapted to engage with the cylindrical arts of rollers 7, and reduced concave en s or trunnions 14. Spacing rings 15, have flush vinner faces, which encircle .the trunnions 10 of rollers 7 and convex outer faces 16- w'hich engage the concave trunnions 14 of rollers .11. A sectional rino- 17 encirclesthe outer series of rollers and is provided, in its inner wall, with a groove 18 conforming in contour to rib 12 on the outer series of rollers, one half of the groove being in oove 8, conforming in contour to y ri'b 6, cylindrical parts 9 adapted to engage each section ofthe ring.'v The sections of the ring maybe held in place by an annular casing consisting of two parts 19 and 20 which may be connected by screws 2l. The retaining rings 15 hold the trunnions of the two series' of rollers in a fixed relation to each other and prevent binding engagement of the rollers.

In use, assuming that sleeve 5 is fixed to ashaft or other rotating element, it will when rotated, cause. rollers 7 to roll thereon and ,this rotation will be imparted to rollers 11,

the rollers all moving in the saine direction e at the points of contact, zbut the inner roll- .ers rotating in opposite direction'from the outer rollers, and the outer-rollersrolling on the inner face of ring 18. The trunnions y of rollers 7 and 11 also roll on rings 15in 'p opposite directions. Assuming that sleeve 5 is stationary and ring 18 turns, the samex effect is produced. I f

While I have described my invention as taking a particular form, it will be underin with .the sleeve, the rollers havin cylindrical trunnions; an annular series o rollers engaging with the rollers of the first series,

the rollers having concave trunnions; spacing rings having a Hush inner face adapted to engage the trunnions of the inner series of rollers, and a convex outer face adapted to engage the trunnions of the outer series of rollers, and means for holding the sleeve and rollers in engagement.

2. An anti-friction bearing' comprising a sleeve having'v an annular rib; an ann series of rollers having annular groovesenga ing with the ribfon the sleeve; 'an annu ar series of rollers havln ribs engaging with the grooves on the ro ers of the first i series'; a sectional ring for holding the sleeve and rollers in engagement with each other and' rovided with an annular groove engaging t e ribs of the rollers on the second series,

the ring being sectioned circumferentially through its groove, and means for securing the sections of the ring to each other.

3. An anti-friction bearing comprising a sleeve' an annular series of rollers engaging with the sleeve, the rollers having cylindrical trunnions; an annular series o rollers engaging with the rollers of the first series, the rollers having concave v trunnionsspacing rings having a flush inner face a apted to engage the trunnlons of the inner series of` rollers, and a convex outer face adapted to engage the trunnions of the outer series of rollers; 'a split ring adapted to hold the sleeve and rollers in enga ement, and means for securing the parts o the split ring to each other.v

4. An anti-friction bearing comprising a sleeve; an annular series of rollers engaglng with the sleeve; an annular seriesof rollers ,20 engaging with the rollers of the first series, the s eeve and rollers being provided with intermeshing ribs and recesses, the rollers of the inner series having cylindrical trunnions and those of the outer series havin trunnions; saacing` rings having a ushlinner face adapte to e age the trunnions of the inner series of ro ers, and a.- convex face adapted to engage the trunnions'of the outer series of rollers, and means'ffor holding the 30 sleeve and rollers in engagement. r In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. l
